The manufacturing process and normalizing technology of EN 10025-6 S460QL1 high strength steel

VLE460 steel plate grade analysis: "VL" stands for the abbreviation of "DNVGL", which is the standard certified by the two classification societies of DNV (Norway) and GL (Germany). VL E460 hull steel characteristics: good welding and other properties. It is suitable for repairing ships and main structures of naval vessels. Naval steel is required to have higher strength, better toughness, blast resistance and resistance to deep water collapse.

BEBON cpompany practice new development concepts, expand in an all-round way, deepen reform and innovation, speed up transformation and upgrading, become stronger, better and bigger, accelerate the implementation of BEBON Steel's EN 10025-6 S460QL1 high strength steel industrial planning, and realize the revitalization and development of enterprises.Fully implement the corporate EN 10025-6 S460QL1 high strength steel market dominant position, comprehensively promote contractual management, and promote the transition from "internal production" to "market operation”.

As the thickness and hardness of EN 10025-6 S460QL1 high strength steel increase, the tendency to crack at the cutting edge increases. In order to prevent the EN 10025-6 S460QL1 high strength steel from cutting cracks, preheating should be carried out before EN 10025-6 S460QL1 high strength steel cutting. Special attention should be paid to preheating to make the entire EN 10025-6 S460QL1 high strength steel interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole EN 10025-6 S460QL1 high strength steel cannot be preheated, the partial preheating method can be used instead.

Corrosion resistance mechanism of EN 10025-6 S460QL1 high strength steel, stainless steel: obvious Cr2O3 film is formed on the surface of stainless steel, and the minimum content of O and Cr (10.5%) is required to obtain continuous protective film to prevent corrosion. If the protective film is damaged, it can recover naturally.

After sales service support personnel pay attention to commitment in their work. In the process of people to people communication, mutual trust is an important factor for the long-term and stable communication.
